To solve them. there has several method.

The one solution rather brute force solution (but I still select to do it with this method = =")
is
1. open device manager
2. select view > show hidden devices
3. then you will see
then I manually right click at each adapter and choose uninstall option.
Wish this may help.

and Then if you didn't want to see them again you can disable Teredo adapter by follow this instruction.

Ubuntu Running in low graphic mode

the cause of this problem is the graphic driver is override by some other software update.

you should download some driver that suit your graphic card and then reinstall.

1. press Ctrl+Alt+F2 (Ctrl+Alt+F8 and BackSpace I can't remember meaning)
then close x server by command "/etc/init.d/gdm stop"
2. sudo ./your driver.run
3. "etc/init.d/gdm start or restart"

Finish then "sudo shutdown now" if you can't back to normal graphic mode = ="
